I have removed an old Franklin stove and stovepipe but the chimney and
ceiling hardware are still in place and I'd like to remove the ceiling
connection (I assume the chimney pipe may come out with it unfortunately).
I can't figure out how the hardware that supports the chimney pipe is
installed in the ceiling. I've looked at it in the attic and I don't see
anything to unscrew. I've posted a photo and illustration at
http://www.billrogers.net/photos/stovepipe

Thanks for any advice.
